CVE-2025-68961
📋 TL;DR
A race condition vulnerability in the camera framework module allows attackers to cause denial of service by exploiting multi-threading timing issues. This affects Huawei devices with vulnerable camera software. The vulnerability impacts availability but does not allow code execution or privilege escalation.
💻 Affected Systems
- Huawei smartphones
- Huawei tablets
- Huawei laptops with camera functionality

⚠️ Risk & Real-World Impact
Worst Case
Camera functionality becomes completely unavailable, potentially affecting applications that depend on camera access including security systems, video conferencing, and authentication methods.
Likely Case
Intermittent camera failures, application crashes when accessing camera functions, or degraded camera performance during concurrent access scenarios.
If Mitigated
Minor performance degradation or temporary camera unavailability that resolves with application restart.
🎯 Exploit Status
Exploitation requires understanding of race condition timing and multi-threaded programming; likely requires malicious application installation or local access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Huawei security bulletins for specific patched versions
Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2026/1/
Restart Required: Yes
Instructions:
1. Check for system updates in device settings. 2. Apply available security updates. 3. Restart device after update installation. 4. Verify camera functionality post-update.
🔧 Temporary Workarounds
Disable camera permissions for untrusted apps
allRestrict camera access to trusted applications only to reduce attack surface
Avoid concurrent camera usage
allPrevent multiple applications from accessing camera simultaneously
🧯 If You Can't Patch
- Implement application allowlisting to prevent untrusted applications from running
- Monitor for camera-related application crashes or failures as potential exploitation indicators
🔍 How to Verify
Check if Vulnerable:
Check device software version against Huawei security bulletins; test camera functionality with multiple concurrent access attemptsCheck Version:
Settings > About phone > Software information (exact path varies by device model)Verify Fix Applied:
